y 4f. An insulator bracket structure compris ing a back frame, a U-shaped bracket having 'its yoke wall secured to said back frame'and with its limb walls extending horizontally, g

said bracket being formed from a single piece of vsheet metal and having side flanges on vits walls7 the flanges of the yoke wall extending alongside of, said back Vframe. and ears. on

said flanges having bolt holes.' whereby the structure may be securedV to a support, deflections at ,the corners of said bracket forming brace walls on the inside of the bracket and gutters `on 'the outside thereof, said back frame having holes in registration with said gutters whereby moisture may escape from the top of said bracket.

ln a device off the classdescribed, a U- .shapedl bracket frame comprising' v.a yoke men'iber and two integral leg members,` said.

members being formed of continuous channel section, the flanges of theyokemember havin integral laterally extending'lugs periiorated to receive attaching bolts for supporting said Ushaped ybracket frame directly -v frame directly uponv a supporting surface, and l a channel bar nesting within and secured to the channelof the yoke member'v to hold the U-shaped bracketmember Vagainst rocking on the lugs.
